Sarah Clark, who has a baby on the way, works at the Pita Jungle when a customer came in earlier in the week and gave her a $900 tip on a $61.30 order.

The unidentified patron wrote on the receipt: “This is God's money — he gave it to us so we could give it to you. God bless."

Clark, whose fiancé is slated to have knee surgery Thursday, will be sidelined taking care of him as they will both be out of work and expecting a child.

“I couldn't believe what I was looking at first because it was such a high amount — $900 is a lot of money," she told KPHO. "And it took a while for it to set in, and once it did I cried for a little while.

“Me being on maternity leave and him being out of work, we're not going to be making any income. So this is really going to help with rent and other bills and things like that.”

Clark said she has seen the customer before and she also happens to be pregnant.

“I had talked to her in the past about my fiancé being injured and him being out of work, and me taking leave and I think it was just a really amazing token of generosity,” Clark said. “It's always wonderful when somebody can do something so generous, or something to really help somebody else's situation out. I plan to pay it forward as much as I can too.”

The waitress is due to deliver her child on January 8.
